Catalytic products international replaces RTO with a VECTOR Catalytic Oxidizer - Case study
A chemical processing facility recently installed a VECTOR Catalytic Oxidizer to replace a competitors Regenerative Thermal Oxidizer. The RTO was installed 5 years earlier and could not provide the reliability demanded by the client. The problem stemmed from a basic mis-application of the technology. As is very common, many air pollution control equipment manufactures have abandoned recuperative ...

Specifications and quality measures for CEMS calibration curves
ABSTRACT Calibration requires special procedures to establish the analysis function of the entire measuring equipment. With the help of a reference method, comparative measurements are carried out and their results are correlated with the simultaneous device output signal. The analysis function to be set up must be representative of the total relationship between the measuring device and the ...

Monte-Carlo model of a gas analyser operating under EN 14181:2014 to investigate achievable uncertainty during emission monitoring
Monitoring of emissions is controlled by the Industrial Emissions Directive (IED), which sets out the requirements for emitters to meet. There are standards in place that, when followed, allow the operators to meet the IED requirements. One of these, EN14181:2014, setting out the quality assurance requirements for continuous emission monitoring, has recently been revised. It is assumed that any ...

A Case Story: LKAB and Gasmet’s CEMS Cooperation
The European Commission has adopted a number of changes in measurement requirements and emission limits for industrial plants. To limit the environmental impact of iron ore mining, leaders in the industry have been taking the necessary steps to keep track of the emissions their processes produce. LKAB, which specializes in the underground mining and production of iron-pellets, prioritizes the ...

`Evaluation of Strategies for Mercury MACT Compliance,` presented at the Coal-Gen 2004 conference
Introduction On December 15,2003, the United States Environmental Protection Agency (U.S. EPA) proposed a rule with two alternatives to permanently reduce mercury (Hg) emissions from power plants. Under one alternative, which is the focus of this paper, the utilities would install controls known as Maximum Achievable Control Technologies (MACT) under section 112 of the Clean Air Act (CAA). The ...

Monitoring of Hydrogen Sulfide in Industrial Processes
Hydrogen sulfide, H2S, is a very poisonous, corrosive, and flammable gas. As such, it needs to be carefully monitored and controlled in industrial processes where it is generated or used. At relatively low concentrations, it has an odour of rotten eggs which effectively works as a warning, but at higher concentrations where it becomes acutely toxic and even lethal, it can no longer be smelled ...

How to tackle the technical challenges of continuous mercury emissions monitoring
Many pollutants such as CO2, NOx and SO2 have been monitored continuously already for decades. In the last years the awareness for the need to measure mercury has also grown, and continuous mercury monitoring is becoming more and more relevant. Especially industries burning coal, oil or waste, share the responsibility to monitor their mercury emissions. Due to its sticky quality and extremely ...

Mercury: measure and control
Following the new EU BREF document for waste incineration, European cement plants have to implement the requirement to continuously monitor and abate mercury emissions. To enable this they will need to apply technologies that measure mercury in the raw gas and optimise sorbent use. In December 2019 the new BREF (Best Available Technology Reference) document for waste incineration was published ...

What is the difference between a gas analyser and a gas monitor?
Technically, there does not have to be any difference at all. However, semantically, “analysis” might suggest something more scientific with higher precision and better performance than a simple “monitor” which possibly suggests a more indicative output where precision is of less importance. With that said, the two words “analyser” and “monitor” ...

Mercury emissions of the German cement industry - Case Study
In December 2019 the new BREF (Best Available Technology Reference) document for waste incineration was published in the EU. One important topic in the Best Available Technology (BAT) conclusions is the request for continuous monitoring of mercury (Hg) emissions. In the BAT conclusions are mentioned so-called BAT-Annual Emission Levels (AELs) for daily averages, with Hg concentrations in the ...

Procedure Z: Quality assurance requirements for X-ray-fluorescence based multi-metals continuous emission monitoring systems at stationary sources case study
Procedure Z outlines the continuing quality control and quality assurance requirements for an x-ray fluorescence based multi-metal CEMS. Procedure Z requires daily checks of the upscale, zero and volume measurement drift. It also specifies quarterly checks of the x-ray fluorescence calibration and of the volume measurement calibration. Finally procedure Z requires that the entire XRF multi metal ...

Continuous monitoring of hazardous smokestack metal emissions using inductively coupled argon plasma atomic emission spectrometry
Introduction Emission of hazardous air pollutant metals from the smokestacks of boilers, incinerators, and furnaces has become a matter of significant environmental concern and the object of increased regulatory scrutiny. At issue, is the ability of large-scale combustors such as these to maintain operation in compliance with the regulatory restrictions put in place to safeguard the public from ...

Marine Monitoring of Emissions of Air Pollutants
Many of us who are not in the marine shipping business probably think of vessels as practical means of transportation, or, when it comes to cruising ships, a place to spend your vacation. However, not all of us realize that large ships also are floating large power plants, with all aspects that come with power plants including potential contribution to air pollution. The environmental aspects of ...
